With Dick Advocaat set to be unveiled (again) as the new Sunderland head coach after a dramatic U-turn, here is everything you need to know about the popular Dutchman.
Advocaat made 543 league appearances during a lengthy playing career, during which he played for the likes of Den Haag, Roda JC and Chicago Sting.
Advocaat is much-travelled as a manager, and has held 11 different managerial roles in the last 11 years. In international football, he has been in charge of Holland, UAE, South Korea, Belgium, Russia and Serbia.
His last job was with Serbia, but he lasted less than four months there, and left in November 2014 after two losses and one draw.
Advocaat has had two spells in charge of the Netherlands. In the first of those, he led them to qualification for the 1994 World Cup, beating England in a vital qualifying game.
Advocaat took over as Rangers manager in 1998, and had huge success initially. He won the treble in his first season, and won the league by a record 21 points the next year.
Things went wrong at Rangers in his third season, as despite heavy investment, they won no trophies. Martin O’Neill’s Celtic won the treble. Advocaat resigned during the next season
Advocaat had a successful time in Russia with Zenit St Petersburg between 2006 and 2009. With the likes of Andrei Arshavin, in the side, they won four major trophies.
Advocaat’s Zenit beat his old club Rangers in the final of the 2008 UEFA Cup. He was later given honorary citizenship of the city of St Petersburg.
Advocaat has faced Sunderland just once in his managerial career. His Rangers side beat the Black Cats 3-1 in Ian Ferguson’s testimonial in 1999.
Advocaat is a hugely experienced manager, and has won four top flight league titles during his career. However, his time at Sunderland was his first spell in England.
The Dutchman steered the Black Cats to Premier League survival after being in charge for just nine games.
